If necessary, the neutral salts which accelerate the removal of the dyes can also be added to the bath only after the actual dyeing temperature has been reached.
- the dyestuff mixtures according to the invention are obtained by conventional printing processes for cellulosic fibers, the single phase, for example by printing with a sodium bicarbonate or other acid-binding agent containing printing paste and subsequent steaming at 100 to 103 0 C, or two-phase, for example by printing with neutral or weakly acidic Printing ink and subsequent fixing either by passing through a hot electrolyte-containing alkaline bath or by over-padding with an alkaline electrolyte-containing padding liquor and then lingering or steaming or treatment with dry heat of the alkaline padded material, can be carried out even strong prints with good contour and a clear white ground. The failure of the prints is only slightly dependent on changing fixing conditions.

- no electrolyte salt is needed for a small depth of color, for an average color depth no more than 5 g / l of electrolyte salt and for large color depths no more than 10 g / l of electrolyte salt.
- a low color depth refers to the use of 2% by weight of dye based on the substrate to be dyed, an average color depth denotes the use of 2 to 4% by weight of dye based on the substrate to be dyed and a large color depth denotes the use of 4 to 10 wt .-% of the dye based on the substrate to be dyed.
- the dyeings and prints obtainable with the dye mixtures according to the invention have clear nuances and have good fastness to lightfastness on cellulosic fiber materials and, in particular, good wet fastness properties, such as washing, flexing, water, seawater, overdyeing and acidic as well as alkaline perspiration fastnesses. In addition, they have good plushing fastness, ironing and rubbing fastness. In particular, however, the very good chlorine fastness is to be emphasized.
- the dye mixtures according to the invention can also be used for the fiber-reactive dyeing of wool.
- This also includes felt-free or low-felt wool (see, for example, H. Rath, textbook of textile chemistry, Springer-Verlag, 3rd edition (1972), pp. 295-299, in particular the equipment according to the so-called Hercosett method (p J. Soc. Dyers and Colorists 1972, 93-99, and 1975, 33-44).
- Dyeing on wool is carried out in an usual and known manner from an acidic environment. So you can, for example, the dyebath acetic acid and / or ammonium sulfate or acetic acid and ammonium acetate or sodium acetate to obtain the desired pH.
- leveling agents such as based on a reaction product of cyanuric chloride with three times the molar amount of an aminobenzenesulfonic acid and / or a Aminonaphthalinsulfonklare or based on a reaction product of, for example, stearylamine with ethylene oxide.
- the dye mixture according to the invention is preferably first subjected to the exhaustion process from acid dyebath having a pH of about 3.5 to 5.5 under the control of the pH and the pH then, towards the end of the dyeing time, in the neutral and possibly weak shifted alkaline range to a pH of 8.5, especially to achieve high color depths, the full reactive binding between the dyes of the dye mixtures of the invention and the fiber bring about. At the same time, the non-reactively bound dye fraction is removed.
- the procedure described here also applies to the production of dyeings on fiber materials of other natural or synthetic polyamides and their mixtures with polyurethanes.
- the material to be dyed is introduced at a temperature of about 40 0 C in the bath, there for some time moved therein, the dyebath then adjusted to the desired weakly acid, preferably weakly acetic acid, pH and the actual color in a Temperature between 60 and 98 ° C performed.
- the dyeings can also be carried out at boiling temperature or in closed dyeing apparatus at temperatures up to 106 0 C. Since the water solubility of the dye mixtures according to the invention is very good, they can also be used with advantage in conventional continuous dyeing processes.
